Unscrew the light head, insert the batteries with the negative terminal down into the battery tube and then screw the light head back on.

Turn on /off

Single press the tail switch to turn the light on/off.

Change modes

When the light is on, twist to loosen then tighten the light head to change modes with the cycle of Firefly, Low, High, Firefly, Low, High, and Strobe.
Method 2:
When the light is on, half press the tail switch (without hearing the “click” sound) to cycle through Firefly, Low, High, Firefly, Low, High, and Strobe.
Method 3:
When the light is on, quick double click (within 1 second) the tail switch to cycle through Firefly, Low, High, Firefly, Low, High, and Strobe.

  1. Thrunite Ti4 review by Jeremy Stokoe on 25/06/2018

    Smooth barrel slips easily into shirt upper arm pen pocket (unlike my Coast G20).
    Firefly mode dim enough to not disturb sleepers (wife & children) when moving around house at night, but still bright enough to easily navigate. Always starts in firefly so that also helps not to disturb (can't use my Klarus XT2C for this stuff). Easy to increase brightness for all quiet house tasks when needed. Love this light, not EDC, but every night with kids carry.
